Researchers say sensitive data can be extracted from air-gapped networks via a wireless router’s blinking LEDs. Researchers have uncovered a new data extraction hole inside air-gapped networks that ...

This simple project aims to build a circuit that can make the LEDs blink with the sound that comes out from the P2 connector. Shown in the video is the LED blinking in action. The design of the ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillator, ...

Almost every micro-based project that I have designed in the past 25 years has had a flashing LED, originally as a “health” indicator, but the feature has expanded to use as a status indicator where ...

You know how it is. You’ve got that new project running, and while it doesn’t consume much power, it also doesn’t give much indication of whether it’s functioning or just sitting there with a dead ...

Lower limb exoskeletons show great promise in helping those who have lost the use of their legs towalk again. However, if a person has been rendered quadriplegic, any hand controls insuch a device are ...

Custom-made malware installed on an offline computer can use a hard drive's LED to send out sensitive data from infected computers to nearby cameras. This Hollywood hacking scenario is now a reality ...
